That cranking compression is about perfect for a street motor,inbetween 180 and 200 psi.Street/strip about 220 and a race motor about 240 psi.
If you are getting below those numbers,which you are not,then your dynamic compression stroke is going to be very short ,giving up hp and torque all thru the rpm band.Effectivly reducing the stroke of the engine and worse yet ,all that stroke you dont use just drags the engine down.
Thos numbers look good to me,inspect the plugs closely for metal particles and back the timing off a few degrees if its worries you.
